LED Matrix Lighting Module Signal Extraction via Segmented Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting arrangements with a cascade of LED modules require unnecessary information extraction and transmission, leading to discarded data and inefficient cable usage, especially when modules are far from the control unit.
Innovation Solution
Incorporating a processing unit within the first lighting module to extract and transmit only essential information to the second lighting module via dedicated interfaces, such as an RGB video interface, eliminating the need for direct connections between the control unit and distant modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all lighting modules are connected directly to the control unit, then each module receives complete control signals, but cable length increases significantly for distant modules
Solution Approach 1:
The system segments the signal transmission path by introducing intermediate lighting modules that act as signal relays. Each module extracts and forwards only the necessary control signals to adjacent modules, creating a segmented communication architecture that reduces individual cable lengths while maintaining complete control coverage.
Solution Approach 2:
Intermediate lighting modules serve as intermediaries between the control unit and distant modules. These modules receive complete control signals from the control unit, extract the necessary information, and forward it to adjacent modules, thereby reducing the effective cable length required for direct connections.
2Loss of information
If the control unit transmits complete signals to all modules, then no information is lost, but unnecessary information is transmitted and processed
Solution Approach 1:
Each lighting module extracts only the necessary control information from the complete signal transmitted by the control unit. The processing unit in each module selectively extracts relevant parameters (such as LED drive signals) and discards unnecessary information, thereby reducing processing energy consumption while maintaining information completeness for the required functions.
Solution Approach 2:
The system transmits complete control signals (excessive action) from the control unit to ensure no information is lost, while individual modules perform partial processing by extracting only the necessary information they need, thereby optimizing the balance between information completeness and processing efficiency.
3Adaptability or versatility
If lighting modules are placed far from the control unit, then installation flexibility improves, but cable length and signal interference increase
Solution Approach 1:
The system enables flexible installation by segmenting the control signal transmission into multiple hops through intermediate modules. This allows lighting modules to be positioned far from the control unit while maintaining manageable cable lengths through the modular relay architecture, where each segment handles a localized portion of the signal transmission.

AI summary
A lighting arrangement with a control unit and two LED lighting modules, each comprising an LED matrix. Control information, including an image signal for generating a light image, can be generated with the control unit for each lighting module, and the light image can be generated with the LED matrix of each lighting module, which the control unit has generated for this lighting module. The control unit is connected to the lighting modules for the transmission of the image signals. The first lighting module has a processing unit and a first interface via which the information for the lighting modules can be extracted from the signal generated by the control unit. The processing unit provides the information intended for the second lighting module at the first interface of the first lighting module, and wherein the second lighting module is connected to the first interface of the first lighting module.
